Individually tailored modular interventions for veterans with complex post-traumatic stress disorder: Outcomes of the ESTAIR program

Tailored modular interventions for veterans with complex ptsd: results from the estair program

A group-based ESTAIR intervention was found to be feasible in veterans with treatment-resistant complex PTSD and produced a significant reduction in symptom severity compared with treatment as usual.

The aim of the study was to evaluate the feasibility and effectiveness of group-based Enhanced Skills Training in Affective and Interpersonal Regulation (ESTAIR) in veterans with treatment-resistant complex post-traumatic stress disorder (complex PTSD, CPTSD) as defined by ICD-11. This single-center, 14-month, nonrandomized study enrolled 90 Croatian war veterans with probable CPTSD who had previously failed to respond to at least two adequate treatments; participants received either group-based ESTAIR plus treatment as usual (TAU; n = 47) or TAU alone (n = 43). ESTAIR was delivered as 18 weekly group sessions focusing on emotion regulation, self-concept, and interpersonal skills. Outcomes were assessed at baseline, post-treatment, and 12-week follow-up using the International Trauma Questionnaire (ITQ), while secondary outcomes were assessed using measures of depression (PHQ-9), anxiety (GAD-7), and alcohol use (AUDIT-C); symptom changes were examined using linear mixed-effects models. Program retention was high: the ESTAIR group had a dropout rate of 4.3% and a follow-up completion rate of 91.5%, compared with a follow-up completion rate of 65.1% in the TAU group. Group x Time effects were significant in favor of ESTAIR for total CPTSD symptoms (p = 0.003), disturbances in self-organization (DSO) symptoms (p = 0.006), and PTSD symptoms (p = 0.042). ESTAIR participants showed reductions at post-treatment that were maintained at follow-up, whereas the TAU group showed minimal change. In conclusion, group-based ESTAIR targeting DSO symptoms was found to be feasible and associated with clinically meaningful reductions in symptoms among treatment-resistant veterans, supporting further randomized controlled trials with longer follow-up periods.
